Jesus, as a man, perfectly yielded to His Father in Heaven. In doing so He was representing the Father perfectly on Earth. Jesus called God His Father and as he later would say…

I came out from the Father and have come into the world; again, I am leaving the world and going to the Father.

(John 16:28 AMPC)

He was on Earth teaching the very words of God because He was not only the Son of God but also God the Son.

“Jesus answered them by saying, My teaching is not My own, but His Who sent Me.”

(John 7:16 AMPC)

Later one of His disciples would say “show us the Father and that will be enough for us.”

“Jesus replied, Have I been with all of you for so long a time, and do you not recognize and know Me yet, Philip? Anyone who has seen Me has seen the Father. How can you say then, Show us the Father? Do you not believe that I am in the Father, and that the Father is in Me? What I am telling you I do not say on My own authority and of My own accord; but the Father Who lives continually in Me does the (His) works (His own miracles, deeds of power).”

(John 14:9-10 AMPC)

The one teaching them was demonstrating what perfect union with God looked like and He was inviting us into that union. He performed miracles, healed the sick, had compassion on the multitudes, carrying out what the prophet Micah said in the Old Testament.

He has showed you, O man, what is good. And what does the Lord require of you but to do justly, and to love kindness and mercy, and to humble yourself and walk humbly with your God?

(Micah 6:8 AMPC)

This was what God said was good and Jesus not only taught this lifestyle but He modeled it every day of His life. His righteousness, as the sacrificial Lamb, was going to be credited to us if we would humbly acknowledge our lack of righteousness and ask Him to give it to us as a free gift.

For our sake he made him (Christ) to be sin who knew no sin, so that in him we might become the righteousness of God (in Him).

(2 Corinthians 5:21 ESV)

His life was lived so well so that we could inherit His goodness as a gift.

For it is by free grace (God's unmerited favor) that you are saved (delivered from judgment and made partakers of Christ's salvation) through [your] faith. And this [salvation] is not of yourselves [of your own doing, it came not through your own striving], but it is the gift of God; Not because of works [not the fulfillment of the Law's demands], lest any man should boast. [It is not the result of what anyone can possibly do, so no one can pride himself in it or take glory to himself.]

(Ephesians 2:8-9 AMPC)
